Setting up existing security system

I have an existing alarm system, when I connected it to my WiFi non of the sensors would connect. I’ve tried all online troubleshooting methods.

Hey @Odieo84. Are you setting up a Ring Alarm system, or another brand’s system? Only Ring Alarm Contact Sensors will connect and be usable on a Ring Alarm Base Station, so you will need to ensure that both products are Ring products. Once the Base Station is connected to wifi, you will be able to set up each contact sensor under Set Up a Device > Security Devices > Sensors > Contact Sensor and following the steps in app.
